The safety relay is a key component in safety control circuits. It receives safety control signal inputs and outputs relay switch signals that are integrated into the equipment's control loop. The relay supports wide voltage (16-35 VDC) control switch signals and achieves a safe and reliable isolation circuit through technologies such as triple redundancy, automatic protection, and contact welding protection. It supports single or dual-loop operation and is compatible with both rail-mounted and base-mounted installation methods. The product complies with IEC61508 standards, achieving safety integrity level (SIL) 3.
